ABSTRACT
<p><b>OBJECTIVE</b>To study the inhibitory activity of Aeschynanthus maculatus on alpha-glucosidase.</p><p><b>METHOD</b>The inhibilitory model of in vitro alpha-glucosidase was established. Active extracts of A. maculatus were isolated and identified bymultiple chromatographic methods, and their molecular structures were identifiied by spectral techniques.</p><p><b>RESULT</b>Seven coumpounts were isolated from A. maculatus and isolated as lupeol(1), stigmasterol(2), ursolic acid(3), stigmast-5,22(E)-diene-3beta-ol(4), beta-daucosterol(5), 3-hydroxy-12-taraxasten-28-oic-acid(6) and oleanic acid(7). Compounds 1 (IC50 25.41 mg x L(-1)),3(IC0 4.42 mg L(-1)),4(IC50 11.50 mg x L(-1)),6(IC50 14.17 mg x L(-1)) and 7(IC50 2.88 mg x L(-1)) had higher inhibitory activities than that of acarbose (IC50 1103.01 mg x L(-1)) as the positive control drug.</p><p><b>CONCLUSION</b>Compound 1-7 were isolated from this plant for the first time. Compound 6 was isolated from Gesneriaceae family for the first time. Compound 7 was isolated from Aeschynanthus genus for the first time.</p>
